摘要：

The electrochemical reaction of H(2)O(2)was promoted by an electrode modified withN,N-diethyl-N-(2-methoxy-ethyl)-N-methylammonium bis(trifluoromethylsulfonyl)imide (DEME-TFSI) and hybrid polymer/silica particles, which consisted of an ionic liquid-type polymer brush decorated with silica particles (PSiP). The electrode was prepared by dropping an acetonitrile solution of homogeneously dispersed PSiPs and DEME-TFSI on a glassy carbon (GC) electrode and drying. During cyclic voltammetry in the presence of 3.0 mM H2O2, the reduction current at -0.400 mV increased from 0.9 to 3.3 mu A compared with the unmodified GC electrode, demonstrating that the electrochemical reduction of H(2)O(2)was promoted on the PSiP/DEME-TFSI-modified electrode.
